I'm going to set this CF item back to Waiting on Author, because (a) there doesn't seem to be an actual concrete patch presented at the moment, only a stack of hard-to-follow deltas, and (b) the patch certainly needs updates for the extension mechanism and committed FDW API anyway. > It requires a small change to the FDW api > (fdw-api-add-serverid-userid.patch).

FYI, I removed those fields from the committed API patch. I don't think it's a good idea to cache potentially-changeable things in a plan node when you can perfectly well fetch them at runtime. Caching user OID is flat wrong anyway, as there's no guarantee that a cached plan will be executed under the same userid it was made with. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
